CY8C5367AXI-108 67MHz PSoC 5 MCU | Infineon
MPN： CY8C5367AXI-108 ✓ 啟用中CY8C5367AXI-108 概覽
A PSoC is a mixed-signal microcontroller that combines a processor core with configurable analog and digital peripheral blocks. Within the semiconductor hierarchy, the CY8C5367 belongs to the microcontroller and embedded-processing family, while its programmable analog and digital resources place it in the broader PSoC system-on-chip category. This integration allows control logic, sensing interfaces, communications, and timing functions to share one programmable device.
The CY8C5367 combines a 67 MHz Cortex-M3 core with 128 KB flash and 32 KB SRAM. Its USB, I2C, and SPI interfaces support direct connections to USB peripherals, sensors, memories, and industrial communications equipment. The 100-TQFP package provides 100 external connection points, giving the design substantial mixed-signal and general-purpose I/O availability compared with smaller microcontroller packages.
Programmable mixed-signal control is the central architectural benefit. Designers can configure digital functions such as timers, counters, serial interfaces, and programmable logic, while analog resources support measurement and control functions. This configurable approach can reduce reliance on discrete peripherals when the required routing and timing can be implemented within the PSoC architecture.
Typical uses include industrial control panels, USB-connected data acquisition, sensor conditioning, programmable logic controllers, communications equipment, and compact embedded control systems. The combination of USB, serial interfaces, moderate on-chip memory, and a high pin count is especially useful when a design needs several external connections without moving to a larger or more specialized controller.
PCB implementation should account for the 100-pin TQFP footprint, power-supply integrity, decoupling, clock routing, and the exposure of debug and programming interfaces. Analog and digital return paths require deliberate grounding, while unused pins and externally exposed programming functions should be reviewed against the system security requirements before production release.
This product record combines the core PSoC 5 specifications, pin-compatible candidate context, interface-level application guidance, and practical design checks. It is intended to accelerate component selection while keeping package reuse, firmware compatibility, and PCB verification as explicit engineering tasks.

典型應用
CY8C5367AXI-108 適用於 6 應用s: Industrial Control and HMI, USB Data Acquisition, Sensor Conditioning and Edge Measurement, Programmable Logic Controller, Communications Gateway, Precision Control and Timing System.
Industrial Control and HMI
The CY8C5367AXI-108 fits industrial control panels and human-machine interfaces that need deterministic 32-bit processing, programmable mixed-signal functions, and multiple communication paths. Its Cortex-M3 core operates up to 67 MHz, while 128 KB of flash supports application code, configuration, and protocol handling. USB, I2C, and SPI can connect a host computer, analog sensors, memory devices, and expansion hardware without requiring several discrete interface controllers. The 100-pin TQFP also exposes a large number of signal-routing options. For production use, verify the operating-temperature grade, isolate external field wiring, provide clean power rails, and validate timing across the full industrial temperature range.
推薦
USB Data Acquisition
The CY8C5367AXI-108 is appropriate for USB-connected data-acquisition equipment where a host computer needs frequent control and measurement updates. A 67 MHz Cortex-M3 core provides processing capacity for sampling coordination and protocol tasks, while 128 KB flash and 32 KB RAM support firmware and working data. The integrated USB interface reduces the need for a separate USB controller, although transceiver, connector, protection, and signal-integrity design remain necessary. Configure the PSoC analog and digital blocks to match the sensor signal and timing requirements, then validate USB enumeration, clock tolerance, power-state transitions, and cable behavior before production.
推薦
Sensor Conditioning and Edge Measurement
The CY8C5367AXI-108 supports programmable sensor-conditioning and edge-measurement systems that combine analog monitoring with digital control. Its PSoC architecture can implement configurable signal acquisition, thresholding, timing, and communication functions around the 32-bit Cortex-M3 core. With 128 KB of flash and 32 KB of RAM, the controller can combine sensor processing, calibration, and serial reporting in one device. The 100-TQFP package offers extensive I/O for external sensors and actuators, but careful partitioning between analog and digital signals is essential. Verify the configured converter, comparator, routing, and sampling specifications in the manufacturer datasheet before relying on a specific measurement chain.
推薦
Programmable Logic Controller
The CY8C5367AXI-108 can serve as the core of a compact programmable logic controller combining deterministic control, serial communications, and configurable mixed-signal functions. Its Cortex-M3 processor runs up to 67 MHz, providing headroom for protocol processing and control tasks, while 128 KB flash accommodates application logic and 32 KB RAM supports runtime state. USB provides a modern service and programming interface, and I2C or SPI can connect sensors and output modules. The 100-TQFP footprint supports numerous discrete inputs and outputs. During design review, check interrupt latency, timer resources, watchdog behavior, bootloader compatibility, and isolation requirements for field-wired channels.
推薦
Communications Gateway
The CY8C5367AXI-108 is suitable for compact communications gateways that aggregate data from serial sensors and forward it through USB or another host interface. Its 67 MHz Cortex-M3 core and 32 KB RAM support protocol conversion, buffering, and supervisory logic, while the programmable mixed-signal architecture can support local monitoring functions. I2C and SPI provide access to sensors, transceivers, and storage devices, and USB offers a direct connection to a host or service interface. The design must carefully partition communication routing from sensitive analog paths and account for ESD, surge, and ground-loop requirements on externally accessible lines. Validate baud-rate tolerance and protocol timing under worst-case clock conditions.
推薦
Precision Control and Timing System
The CY8C5367AXI-108 fits embedded control systems that coordinate programmable mixed-signal functions with high-rate digital logic. The 32-bit Cortex-M3 core operates up to 67 MHz, while PSoC programmable blocks can implement timers, counters, serial functions, and logic close to the analog front end. This architecture can shorten signal paths and reduce discrete component count in measurement-and-control equipment. The 100-TQFP package provides extensive connections to sensors, actuators, and debug hardware. Designers should establish clock-domain relationships, constrain timing-critical routes, isolate switching return currents, and verify startup behavior. Firmware should include calibration, watchdog recovery, and fault-state handling for field reliability.

設計說明
Design the CY8C5367AXI-108 supply network from the manufacturer power-application guidance rather than general MCU assumptions. Place the required bypass capacitors at the package power pins with short, low-inductance connections, and provide a clean return path to the associated ground plane. Separate noisy switching returns from analog and communications routing. Confirm the permitted voltage, decoupling configuration, startup sequence, and USB current state in the manufacturer datasheet before schematic release.
Treat the 100-TQFP land pattern as a high-pin-count routing problem and use the official package drawing to define pad dimensions and courtyard clearance. Preserve access to programming, reset, clock, and debug signals. Route USB differential pairs as a controlled impedance pair with continuous reference plane and minimal stubs. Because PSoC routing can be programmable, reserve unused peripheral pins and avoid placing sensitive analog inputs beside high-speed switching nodes wherever the board stack-up permits.
Do not assume that a related CY8C PSoC 5 part is a production drop-in replacement solely because its package name appears similar. Validate pin multiplexing, analog-route assignments, interrupt vectors, bootloader behavior, clock limits, memory map, USB implementation, and peripheral resources. For a cross-brand migration, also check startup latency, development-tool support, peripheral equivalence, and driver dependencies. Run hardware-in-the-loop tests across voltage and temperature limits after any substitution.
Keep clock, USB, serial, and fast programmable-logic routes away from sensitive analog inputs and noisy external connectors. Match USB impedance to the PCB stack-up, provide a continuous ground reference, and observe the required separation from other high-speed paths. For SPI and I2C, minimize capacitance on clock and data nets and add damping or series termination only when waveform measurements show a need. Grounding and return-current continuity are especially important when the PSoC analog blocks share the same package as digital logic.
